To all wkomit may concern:

Be it known that I, CHARLES E. BROWN, acitizen of the United States, residing at Lawton, in the county of Comanche and drawings.

This invention relates to certain improve ments 1n sluices and it is an ob ect of the invention to provide a device of this general character having novel and improved means whereby efi'ective agitation may be imposed upon the value bearing material and where by a materially large tonnage is afforded.

It is also an object of the invention to provide a novel and improved device of this general character comprising a box mounted for vibratory movement together with an agitating member positioned within the box and also mounted for vibratory movement, and wherein said box and agitating member are operated in unison but in reverse direc tions.

A still further object of the invention is to provide a device of this general character including a box mounted for vibratory movement and wherein said box is provided with novel and improved means for collecting the heavy material or concentrates.

Furthermore it is an object of the invention to provide a novel and improved device of this general character including a box mounted for vibratory movement and wherein the discharging end portion of the box is provided with a well adapted to collect the heavy material or concentrates and wherein said well is provided with a valve-controlled discharge opening for emptyingthe well of the matter collected therein.

The invention also has for an object to provide a novel and improved device of this general character including a box mounted for vibratory movement and provided at its discharging end portion with a collecting well, together with an agitating member coacting with the box and with the well.

Also an Object of the invention is to provide a novel and improved device of this general character including a vibratory boxtogether with a conveyer coacting with the discharge end of the box, and wherein said conveyer coacts with the upper portion of the box to collect the by-products or waste material. r

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved sluice whereby certainimportant advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

V The novel features of the invention will hereinafterbe definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a longitudinal vertical sectional view taken through one end of a device constructed in accordance with an embodiment of my invention;

Fig. 1 is a longitudinal vertical sectional view taken through the opposite end portion of the device asherein disclosed;

Fig. 3 is a sectional view taken substantially on the line 33 of Fig. 1;

Fig. 4 is a fragmentary View in elevation illustrating a bumper as herein included;

Fig. 5 is an enlarged fragmentary view in top plan of the discharging end portion of the box;

Fig. 6 is a sectional view taken substantially on'the line 66 of Fig. 5;

Fig. 7 is an enlarged fragmentary View taken transverselyof the box illustrating in detail an embodiment of agitating members;

Fig. 8 is a fragmentary sectional view taken substantially on the line 8- -8 of Fig. 7

Fig. 9 is a fragmentary sectional View taken substantially on the line 99 of Fig. 7 and Fig. 10 is an enlarged fragmentary sectional view illustrating a lining which may be employed in connection with the box.

As disclosed in the accompanyingdrawings, 1 denotes a suitable base or foundation of predetermined dimensions and mounted upon the skids or runners 2 arranged in parallelism and disposed longi tudinally of the base or foundation. The skids or runners 2 permit the device to be readily transported from one locality to the other although it is to be understood that when in operation the base or foundation 1 is adapted to be raised to a predetermined elevation and on a slight longitudinal incline.

Resting upon the base or foundation 1 and disposed longitudinally thereof are the parallel angle beams 3 arranged in predetermined transverse spaced relation. Suit ably secured to the beams 3 are the up standing trusses lof any ordinary or pre ferred construction and which are arranged in :pairs in" longitudinally spaced relation, the trusses of each pair being transversely alined. Each pair of trusses have their upper portions tied or connected by the transverse irons 5 upon which rest the parallel beams 6 extending longitudinally of the foundation and positioned intermediate the trusses 4:, as is particularly illustrated in Figs. 2 and 2 The upper portion of the trusses l intermediate the irons 5 are provided with the transversely ali-ned bearings 7 in which are rotatably supported the angular extremities 8 ofjthe substantially U-shaped hangers 9. The-base or intermediate portions 10 of the hangers 9 are pivotally engaged, as at- 11, with the transverse strips 12 secured to the upper edges of the sides 14 of the box 13.

By this arrangement it will be perceived that the boxB may be'readily and conveniientlyvibrated.

The discharge end of the box B is open while the opposite end 15 is arranged on a predetermined downward and forward incline and the sides 14 of the box B immedi ately adjacent the closed or receiving end 15 are provided with theupstanding extensions or wings 16. The end portion of the box B provided with the wings or extensions 16 underlies the discharge end of the hopper H into which the value bearing material to be separated is initially deposited in any manner which best suits the requirements of -practice.

' The closed end 15 at its upperportion is provided with the outwardly directed and transversely spaced webs 17 connected by the'rod 18. Pivotally. engaged withthe' rod 18 is the rigid link or plate 19 which plate or link is also pivotally engaged, as at 20, with the crank 21 of the shaft 22 supported by the transversely alined bearings 23 suitably mounted upon thebase or foundation 1. Que end portion of the shaft 22 is operatively engaged, as at 24, with the driving shaft 25 extending longitudinally of the base or foundation 1 and positioned adjacent the outer side ofone of the angle beams. 3. The shaft 25 is suitably mounted with in the bearings 26 carried by the "baseor foundat1on l, and said shaft 25 at a predetermined point intermediate its length has affixed thereto the pulley 27 adapted to be connected with any suitablesource or oweei Whilel show a pulley 27 aliixed "tothe shaft and with which a belt is adapted to coact, it is to be understood that any desired means may be employed for impar'tingthe requi-- site rotation to the shaft 25.

Thebox B is of such a length as. to have its discharge end extend beyond thefa'djacent end portion of the base or foundation- 1. and said extended portion is provided 111 its bottom 28 with the transversely spaced openings 29 in communication withrthe receptacles or wells30 dependingfrom the extended portion of "the box B. The bottom of each of the wells orreceptacles 30 is open;

and has coasting therewith a slide valve 31.,

heavier material or concentrates retained within the receptacles or wells 30'iis substantially virgin metal. a

The beams 6 are also provided with the transversely alined bearings 32 with which are rotatably engaged the angular extremia ties 33 of the substantially U-shaped hang ers 34. The basesor intermediate portions 35 of said hangers are pivotally engaged, as at 36, with the elongated plate 37 positioned intermediate the sides 14 of the box B and: substantially entirely closingthe same. The plate 37 is also positioned adjacent the/upper edges of the sides 14 and is of such a length as to extend from substantially the inner endsof the wings or extensions 16 to the forward edges ofthe openings 29 so that said plate will overlie the receptacles or wells 30 hereinbefore-referred to.

The portion of the plate 37 adjacentthe discharging end of the box has pivotally engaged with theupper surface thereof, as at 38, the inwardly directed rigid linkor plate 39 which is also operatively engaged with the crank 40 of the transverse shaft 41,

each end portion of which being rotatably supported by a bearing42 extending upwardly from the base or foundation 1.

An end portion of the shaft 41 is operatively engaged, as at 43, with the shaft 25 hereinbefore referred to whereby it will be at once understood that the-shafts 22 and 41 will be caused to rotate in unison. It is also to be noted that the cranks 21 and 40 are reverselydirected so that while the box B and plate 37 will be reciprocated or vibrated in unison, the movements thereof will be in reverse directions.

The sides 14 of the bOXB adjacent the discharge end thereof have engaged therewith through the medium of the transverse member 44, the upstanding sides of an apron 46, said apron andits sides extending forwardly converging walls 49 terminating in substantially parallel portions intersecting the inner portion of the apron 46,

and the upper marginal portions of said substantially parallel parts 50 are-operatively engaged with the member 44 hereinbefore referred to. The portions 51 of the apron 46 intermediate the parallel parts 50 are capable of vertical adjustment so that the same may be raised or lowered relative to the underlying portion of the discharging end of the bottom 28 of the box B or that portion of the bottom 28 of the box B in advance of the openings 29. The por tions 51 serve as skimming elements whereby it will be at once self-evident that the lighter material will be caused to pass over the elements or portions 51 so that the waste or by-products comprised in the lighter material may be carried upwardly of the trough 47 while theheavier material or concentrates not collected within the wells or receptacles 30 may be discharged upon the oppositely directed and downwardly inclined chutes 52. The chutes 52 as herein embodied are supported in applied position through the'mediumof the angle irons 53suitablysecured to the base or foundation 1. l i l l Underlying the plate 37 and co-extensive therewith is a supplemental plate 54. The

plates '37 and 54 are secured one to the The plate 54 is provided with a plurality of depending agitating members 56 which i may be as desired, and it is preferred that certain of said members 56 be elongated, as indlcated at 5'7, so as to extend within the wells or receptacles 30 so that the heavy material or concentrates collected thereby may also be agitated for a purpose which is believed to be clearly apparent to those skilled in the art to which my invention appertains.

It has also been found of advantage to provide the end of the plate 37 with the upstanding guard or shield 58 extending above the discharge opening 59 in the hopper H, whereby it will be perceived that the material as delivered from the hopper Hwill be caused to fall within the receiving end portion of the box B.

It is also to be understood that suitable means is to be employed for causing the byproducts or waste material delivered to the trough 47 to travel upwardly thereof and as herein disclosed, this result is accomplished through the medium of the endless members 60 operatively engaged with the transverse shafts 61 positioned adjacent the opposite end portions of the trough 47.. The endless members 60 are connected by of the box B. It will therefore be at onceselfevident that the converging walls 49' will retard the flow or travel of the value bearing material and increase the depth thereof at the discharging end portion of the box B which provision, in practice, has proven of utmost importance.

The vertical adjustment of the free end portions of the skimming elements 51 permits the same to be set in accordance with the necessities of practice and while this vertical adjustment may be efi'ected in any desired manner, I prefer to employ the arrangement disclosed in the accompanying drawings and wherein a transverse beam 64 is carried by the discharging end of the box B and disposed above the straight portions 50 of the wa1ls49. Depending from said beam 64 are the threaded shanks or members 65 operatively engaged with the free ,end portions of the skimming elements 51 through the medium of the nuts 66' arra i'iged above and below said elements.

While the agitating members coacting with the plate 37 may be as desired, I find it of especial advantage and importance to employ the members M as particularly illustrated in Figs. 7, 8 and 9. In this embodiment, the members M are arranged in staggered relation as particularly disclosed in Fig. 9 and each of said members M is substantially U-shape in form with its side arms 67 disposed on a predetermined rearward in- .cline as disclosed in Fig. 8 so that theintermediate or base portion 68 of said member will be inclined downwardly and forwardly. By this arrangement it will be perceived that upon the forward movement of the plate 37" the intermediate or base portion (ibwill serve in the nature of a scoop so that in addition to agitating the value bearing material it will cause said material to advance or move forwardly. To further effect the requisitetravel of the value bearing material I also find it of extreme importance to have the side arms 67 of the member disposed transversely in forward convergence, as is be lie-ved to be clearly illustrated in Figs. 7 and 9. lVith the side members 67 and the base or intermediate 68 arranged as just described, it will also be self-evident that upon the rearward movement of the plate 37, the member M will pass freely therethrough without materially effecting the flow ,of the valuebearing material. Theupper or free extremities of the side arms 67 are angularly disposed; as at 69 and said angular portions 69 contact with the under face of the plate 37* and are suitably secured thereto, asindicated at 70.

. If preferred, the box B or more particularly the bottom 28 thereof may be provided with a lining L as indicated in detail-in Fig. 10. The lining L as herein disclosed comprises a bottom or lower lamination 71 of a relatively fine metallic mesh, and restingupon the lamination 71 is a second lamination 72 of a coarse porous textile fabric. Resting upon the lamination 72 is a third lamination 73 consistingof a metallic fabric of a relatively large mesh and of a heavier material than the lamination 71. The lining L serves as an effective medium to retain flour goldor the like and the uppermetallic lamination 73 serves as an effective guard or protection'in the event the agitating members 56 or M should come in contact with said lining L.

It has also proven of advantage in practice to provide means coacting with the box B to bringthe same to an abrupt stop on its forward movement. As herein embodied, I provide the rear edgev or face of a pair of triisses 4: withthe rubberrfaced blocks 74:

From the foregoing description, it i is tho gh t ou tha a sl i e c ns ruct ed in accordance with my invention is of an extremely simple and comparatively in.- expensive nature and is particularly well adapted for use by reason of the convenience and facility with which it maybe assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice,except as hereinafter claimed.
